Senior DevOps Engineer (AI Infra) Remote UK Job Role As a Senior DevOps Engineer, you’ll be a hands-on technical leader at the heart of our engineering organisation, owning the design, delivery, and reliability of our most critical infrastructure. You’ll drive the automation and continuous improvement of our deployment pipelines, cloud and bare metal environments, and Kubernetes-based orchestration layer — ensuring our platform scales reliably to support high-performance AI and GPU workloads. You’ll set the standard for engineering excellence, partnering with Platform, SRE and Product Engineering teams to align on strategy, shape technical direction, and embed a true DevOps culture across the organisation. Championing infrastructure as code, observability, and a bias toward automation at every layer of the stack, you’ll influence design decisions and cross-team ways of working that raise the bar for how we build and operate systems at scale. What You’ll Do Design, build, and continuously optimise CI/CD pipelines in GitHub Actions to support fast, reliable, and repeatable software delivery. Own and evolve Infrastructure as Code practices using Terraform and Ansible, ensuring infrastructure is version-controlled, peer-reviewed, and consistently provisioned across dev, staging, and production. Manage and maintain hosted application environments, ensuring high availability, scalability, and smooth deployment of services into production. Partner closely with Go engineers to deeply understand their development workflows and release processes, identifying and removing friction points that slow delivery. Own and continuously improve the observability stack — from instrumenting services with logging, metrics, and tracing, to building dashboards, alerts, and runbooks that enable proactive detection and faster resolution. Measure and improve developer experience and productivity. Take responsibility for the continuous delivery pipeline for build and deployment. Streamline and standardise the release process for Go services, working with engineering teams to implement versioning strategies, automated testing gates, and progressive delivery patterns such as canary or blue-green deployments. Identify and eliminate bottlenecks across the software development lifecycle, reducing the time between a commit and a production deployment without compromising quality or stability. Champion a self-service DevOps culture, enabling development teams to own their deployments and operational concerns through well-designed tooling, documentation, and guardrails. What You Bring Proven experience in DevOps engineering and best practices. Deep understanding of Kubernetes, Helm and other containerisation-related tooling. Demonstrable scripting ability in Python, Shell and Ansible. Strong knowledge of branching and deployment strategies, including the use of Git-based version control. Experience with CI/CD workflows, observability, security and automation best practices. Why Join Us? What sets us apart is our blend of modern technology, competitive benefits, and an open, welcoming work culture that enables our people to thrive. Here are just some of the great things you can expect: 25 days of annual leave. A culture that emphasises results over hierarchy, process and ego: we place great emphasis on the quality, ingenuity and creativity of work. Open communication and regular feedback: we value smooth collaboration, direct and actionable feedback, and believe that leading with empathy and a growth mindset makes us better together. Dedicated learning time to focus on new skills, projects or interests outside your day-to-day job. Health & wellbeing support, including private medical insurance. A cycle-to-work scheme, as part of our commitment to building a sustainable business. Subscription access to a variety of gyms and wellbeing apps. Participation in the company shares programme. Enhanced parental pay & leave.
